The film is often cited as a direct inspiration for the Indiana Jones franchise of films, with many of the scenes in Secret of the Incas bearing a striking resemblance in tone and structure to scenes in Raiders of the Lost Ark. Throughout Secret of the Incas, the main character, Harry Steele, can be seen wearing the "Indiana Jones" outfit - brown leather jacket, fedora, tan pants, an over-the-shoulder bag, and revolver.
